If you’ve spent any time in Mexico — or even just scrolling through Mexican social media — you’ve hit a wall of words that aren’t in any dictionary. That’s not an accident. Mexican Spanish has a rich, living slang layer that runs parallel to the textbook version, and they don’t always agree.
This isn’t a complete glossary. It’s the twenty words that come up constantly, across cities, across age groups, across contexts. Learn these and conversations will start making a lot more sense.
Greetings and vibe
¿Qué onda?
“What wave?” in literal terms. In practice, it’s the all-purpose Mexican greeting — the equivalent of “what’s up.” Between close friends it’s casual and warm. Said with a different tone — “¿qué onda contigo?” — it turns into something more like “what’s your deal?” The word onda (wave) also means vibe or energy in general: buena onda means someone is easy to be around; mala onda means they’re not. Full breakdown →
Sale
The casual way to agree to anything. “De acuerdo” is technically correct; nobody says it in informal settings. Sale is lighter, faster, more Mexican. ¿Nos vemos a las 8? — Sale. The double form “sale, va” adds extra confirmation — both words mean the same thing, but together they carry the weight of a handshake. Full breakdown →
¡Órale!
One word, many moods. Agreement: órale, nos vemos. Excitement: ¡órale, qué chido! Encouragement or urgency: órale, apúrate. Surprise: órale, no lo sabía. The meaning comes from context and tone. If you’re not sure what’s happening in a conversation, saying órale is usually a safe response. Full breakdown →
¿Qué onda, perro?
The streetwise version of ¿qué onda? — adding perro (literally: dog) shifts the register into CDMX youth speech and barrio culture. It maps to “sup, homie” or “what’s good, dawg.” Unlike carnal, which implies a real relationship, “perro” can be casual or even ironic between people who just want to set a relaxed tone. Full breakdown →
People
Güey
Before anything else, understand güey. It’s everywhere. It means roughly “dude” or “bro” but functions as a verbal filler, a term of address, and a general-purpose exclamation depending on tone. ¿Qué onda, güey? — What’s up, man. Technically it comes from the word for a castrated ox. Nobody thinks about that anymore. It’s as neutral as “dude” in California. Full breakdown →
Carnal
From carnalis — of the flesh. Originally meant blood brother. Now it means anyone who’s got your back the way a blood brother would — a close friend, someone from the same neighborhood, someone you’d trust in a serious situation. Carnales (plural) carries extra weight in norteño music and Chicano culture. More intimate than güey — carnal is something earned, not handed out. Full breakdown →
Fresa
Literally “strawberry.” In slang, it refers to someone who’s preppy, proper, or from a higher social bracket — someone who speaks very polished Spanish, shops at certain stores, has a particular way of carrying themselves. It’s not always an insult; it’s often delivered with affection or light irony. Ese antro es muy fresa. — That club is very upscale. Full breakdown →
Reactions
¡Híjole!
A euphemism for something stronger starting with the same syllable. The abuelita-approved exclamation for surprise, mild alarm, or genuine shock — depending on volume and tone. Safe in all company: dinners with parents, professional settings, in front of kids. The spelling varies (híjole or íjole) — both are fine, regional preference, no rule. Full breakdown →
No manches
The clean version of a stronger expression. No manches is the equivalent of “no way,” “are you serious,” or “come on” — used for disbelief, mild frustration, or surprise. No manches, se me olvidó el dinero. — No way, I forgot my money. Safe enough to use in front of your girlfriend’s parents, unlike its cousins. Full breakdown →
¡Aguas!
The informal warning. Means watch out, careful, heads up. You’ll hear it on the street, in kitchens, in traffic. It comes from when people in older cities would throw dirty water out of windows and shout ¡aguas! as a warning. Now it’s just the general heads-up signal. ¡Aguas con el escalón! — Watch the step. Full breakdown →
Ni modo
“Not a way” — no workaround, no use fighting it. But it’s not resignation in the defeated sense. It’s closer to equanimity: the situation is what it is, now what? Flight canceled — ni modo, a buscar hotel. Someone didn’t show up — ni modo, nos vamos sin él. It’s used to close a chapter, not complain about one. Full breakdown →
Time and place
Ahorita
The word that trips up foreigners more than any other. It technically means “right now” or “very soon.” In practice it means somewhere between “in a moment” and “don’t count on it.” If a waiter says ahorita, your food is coming. If a contractor says ahorita termino, start making other plans. Treat it as “eventually” until proven otherwise. Full breakdown →
Antro
A nightclub, bar, or dive — any place people go to drink and dance, usually late. Not a neutral word: it carries a slightly underground, sweaty, fun connotation. ¿Vamos al antro? — Are we going out tonight? The caliber can range from a neighborhood cantina to a rooftop club in Polanco. Context usually makes the tier clear. Full breakdown →
Money and work
Lana
Literally “wool” — from sheep, one of the original portable forms of wealth. The metaphor stuck. Lana is the casual word for money, class-neutral and comfortable. What separates it from dinero is tone: dinero belongs in a bank or a contract; lana is what you’re short on when the bill arrives. ¿Traes lana? — You got cash? Full breakdown →
Chamba
The casual word for work or a job. Not the sterile trabajo — chamba implies hustle, the thing that keeps the lights on. Tengo mucha chamba esta semana. — I’ve got a lot of work this week. ¿Encontraste chamba? — Did you find a job? A chambeador is someone who works hard — a grinder, in the positive sense. Full breakdown →
Lifestyle
Chela
Beer. Simple, useful, universally understood. Una chela, por favor will get you a smile anywhere in Mexico. Plural: chelas. As in: vamos por unas chelas — let’s go grab some beers. No deeper cultural history required. Full breakdown →
Crudo
If you were out the night before and you’re feeling rough, you’re crudo (masculine) or cruda (feminine). The Mexican Spanish word for a hangover, literally meaning “raw.” Estoy muy crudo hoy. — I’m really hungover today. The traditional cure is caldo de pollo, Pedialyte, or just time. Full breakdown →
Chido
The all-purpose positive — cool, nice, good, great. Feminine: chida. It’s not edgy slang; it’s just how you express approval without sounding formal. ¡Qué chido lugar! — What a cool place. Tu chamarra está muy chida. — Your jacket is really nice. You can’t go wrong with it. Full breakdown →
Chafa
The opposite of chido. Cheap, low-quality, fake, not worth it. Este teléfono es muy chafa. — This phone is total junk. Una bolsa chafa. — A knockoff bag. It can be used affectionately when describing something so bad it’s funny, or flatly when something genuinely disappointed you. Full breakdown →
Neta
The truth. The real deal. La neta is the honest version of something — what actually happened, what someone actually thinks. A neta, no me gustó. — Honestly, I didn’t like it. ¿Cuál es la neta? — What’s the real story? It implies you’re cutting past the polite version and getting to what’s real. Full breakdown →
Padre
Literally “father.” In slang, it means cool, great, excellent — similar to chido but slightly more emphatic. ¡Qué padre! — How cool! / That’s great! It’s been around longer than chido and skews slightly older in usage, though you’ll hear it across generations. Can be used ironically too: qué padre que no avisaste. — Great, thanks for not telling me. Full breakdown →
These twenty words won’t make you fluent, but they’ll make you legible. Mexicans are generous with foreigners who try — the effort counts, even when the pronunciation needs work.
The best way to absorb this is exposure. Watch Mexican comedians. Listen to Mexican podcasts. Talk to people. The formal stuff you learn in class gives you the structure; the slang is what fills it in.
